Lattice MARS
Measured integrity between offshore inspection campaigns
Lattice MARS provides asset integrity and flow-assurance information from fixed and floating offshore energy infrastructure.
Offshore energy assets are still managed largely through models, surveys and inspection campaigns. Lattice MARS gives operators measured evidence between those campaigns.
Installed Lattice devices are placed on or near offshore assets to capture sensor data, process information at the edge and transfer selected information for inspection planning, model calibration, intervention decisions and life-extension review.
In shallow fixed-bottom wind, information can transfer through the water-air boundary in the magnetic domain. In deeper floating wind and FPSO applications, Lattice MARS can combine acoustic communications below water with magnetic communications across the water-air boundary.
Applications
Fixed-bottom wind, floating offshore wind, FPSOs, moorings, risers, dynamic cables, pipelines, flowlines, substations, cable protection systems and touchdown zones.
What it measures
Motion, vibration, inclination, curvature, fatigue response, cable behaviour, mooring and riser response, pipeline and flowline movement, temperature, pressure, corrosion / CP and flow-assurance sensor data where configured.
Customer value
Measured evidence between campaigns. Better inspection priorities. Stronger model calibration. Earlier warning of abnormal behaviour. Support for intervention, deferral and life-extension decisions..
The problem
Moorings, risers, pipelines, umbilicals and dynamic cables operate in coupled metocean, structural and flow conditions. Periodic inspection can confirm condition at a point in time, but it does not provide a continuous record of movement, vibration, fatigue drivers or flow-assurance behaviour under real operating conditions.
The MARS solution
Lattice MARS installs Lattice devices on or near SURF assets to measure structural response and flow behaviour. Edge processing classifies events locally. Hybrid magnetic-acoustic communications transfer event-driven information to a Lattice Gateway and connected customer systems without wet-mate connectors, dunkers or permanent umbilicals.
Where it fits
MARS is the industrial integrity and flow-assurance page. It should be kept separate from SeaWay Dome. The page should speak to offshore operators, integrity engineers and subsea engineering teams who need measured evidence rather than inferred behaviour.
Customer outputs
- Integrity records for fatigue and movement history.
- Event records and trend information.
- Inspection priorities based on measured behaviour.
- Inputs for OrcaFlex or other engineering models.
- Evidence for maintenance planning, production decisions and life-extension assessments.
Applications
- Mooring integrity and creep monitoring.
- Riser and umbilical response.
- Pipeline walking and touchdown-zone movement.
- Dynamic cable motion and free-span response.
- Slug flow and flow-assurance diagnostics.
- Field-wide integrity monitoring where repeated vessel campaigns are costly.
Measured asset integrity and flow assurance between offshore inspection campaigns.
Installed Lattice devices capture asset behaviour between inspection campaigns.
Lattice MARS processes local dynamic, structural, corrosion and flow-assurance sensor data at the edge and transfers selected information for inspection, intervention, model calibration and life-extension decisions.
WHAT IT MONITORS
Motion, vibration, inclination, curvature, fatigue, corrosion, pressure, temperature, pipe walking, and other key parameters.
HOW IT WORKS
Asset-mounted Lattice devices process sensor data at the edge and transfer selected information through the configured magnetic or hybrid communications route.
WHY IT MATTERS
Operators gain actionable information between inspection intervals and extend asset life safely.
1 - INSTALLED LATTICE FMS
A Lattice FMS is clamped to the CPS approximately halfway between the monopile and touchdown point to capture local structural and dynamic behaviour.
2 - MAGNETIC COMMUNICATIONS & GATEWAY
In shallow water, information crosses the water-air boundary magnetically to an above-water gateway fixed to the monopile handrail, then transfers by radio backhaul to customer or cloud systems.
3 - ACTIONABLE ASSET-INTEGRITY INFORMATION
Outputs support inspection planning, intervention decisions and model calibration, while transferring selected
What this configuration monitors
- CPS movement and bending
- Inclination and curvature
- Water currents
- Vibration and fatigue response
- Temperature and pressure where configured
- Abnormal dynamic events
Configuration Note
Performance is deployment-dependent and should be confirmed against asset geometry, sensor configuration, duty cycle, battery pack and communications path.
